From: Yufeng Mo <moyufeng@huawei.com> mainline inclusion from mainline-v5.15-rc2 commit b81d89487465 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I4CVS3 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i... ---------------------------------------------------------------------- The firmware will not disable mac in flr process. Therefore, the driver needs to proactively disable mac during flr, which is the same as the function reset.
